Villains

Frieza
Frieza (Furīza, Freeza) is one of the worst villains in the Dragon Ball manga and anime. He is a galactic ruler of an unknown race who directs the trade of planets around the galaxy, and his feared for his ruthlessness and power. He is the son of King Cold and Cooler's younger brother. Freezer is also making appearances in several movies, Dragon Ball Z and Dragon Ball GT. His name is a rewrite of "freezer", while his brother's name refers to a cooler.

Cell
Cell (Seru) is a great villain and the ultimate creation of Dr. Gero, designed to have all the capabilities of the greatest fighters that ever lived or visited Earth. The result is a "perfect warrior" with many traits and special abilities. It should be noted that Cell is the only creature belonging to the red ribbon army who does not have the badge of red ribbon on at one time or another. It is also interesting to note that he is one of the few creatures not directly created by Dr. Gero, the others are Android 13, and maybe Android 8. Both Cell's and Android 13's designs were completed by Dr. Gero's Super Computer.

Majin Buu
Majin Buu (Majin Bu), later known as Mr. Buu (Fat Buu, or, or Good Buu), is the first form of Majin Buu seen in the manga or anime. In the series, all forms of Buu are simply called "Majin Buu", but the different forms owe their common name to various video games of Dragon Ball Z. Buu and Babidi have names that are most likely references to the magic words used in Cinderella's fairy tale, "bibid, Babidi, Boo!". In Japanese, Majin Buu is roughly translated as Magic Chef.
